Trust Fails - Specified Domain does not exist or could not be contacted

[Cambio Del Arte]

Hi All,

I am attemtping to set up a (seemingly simple) non-
transitive (external), one-way trust relationship between
2 W2K domains (domA.com is trusted by domB.com) running
in Native W2K mode (NetBIOS is also disabled on
Adapters). However, the trust verification is failing
with the error:

"The secure channel query on domain controller
\\dc1.domA.com of domain dom1.com to domain domB.com
failed with error: The specified domain either does not
exist or could not be contacted"

I cannot account for this error as all tests indicate
that the required connectivity is in place.

Each domain has its own dedicated DNS infrastructure,
however I have manually created respective "primary"
zones and imported the zone files from the corresponding
domains such that all necessary resource and host records
can be queried in each domain/DNS. This is confirmed with
the following succesful tests:

-------------------
nslookup

set q=srv
domB.com

Server: dc1.domA.com.com
Address: 10.10.10.10

domB.com
primary name server = dc1.domB.com
responsible mail addr = administrator.dom2.com
serial = 137
refresh = 900 (15 mins)
retry = 600 (10 mins)
expire = 86400 (1 day)
default TTL = 3600 (1 hour)
-----------------
NLTEST /DSGETDC:domB.com
DC: \\dc1.domB.com
Address: \\11.11.11.11
Dom Guid: r342dw3c-1657-4b8f-8626-ba27509d8d5e
Dom Name: domB.com
Forest Name: domB.com
Dc Site Name: Default-First-Site-Name
Our Site Name: Default-First-Site-Name
Flags: PDC GC DS LDAP KDC TIMESERV WRITABLE
DNS_DC DNS_DOMAIN DNS_FOREST CLOSE_SITE
The command completed successfully
---------------------

I am also able to connect to the file share (with
authentication) \\dc1.domB.com\sysvol

--------------------
I can succesfully query the ldap service on domB using
the ldp.exe tool.
---------------------

These domain are seperated by a firewall, but all
required packets are being passed (DS, LDAP, Kerberos,
etc),no packets are beinf dropped.


Any suggestions?

External trusts REQUIRE NetBIOS. Enable it on the adapters and try again. If
across subnets, you'll need WINS support or lmhosts files.
